Java for Beginners with Hands-On Program and Capstone Project - Save the Book Entity in a list inside Repository

The video tutorial discusses how to save a Book entity from the controller to the repository in a Java application. Initially, it suggests using a list to store Book entities, but highlights the issue of data loss when the program stops. To address this, the video introduces serialization as a method to persist data by converting it into a byte stream and saving it to a file. The tutorial concludes with a plan to apply serialization in the next video.

What is the purpose of creating a list of Book entities in the repository?

What method is used to add an entity to the list in the repository?

What is the significance of the ID returned after saving a Book entity?

What happens to the data stored in the list when the program stops running?

How can we ensure that data persists even after the application stops?

Explain the process of serialization as mentioned in the text.

Describe the difference between serialization and deserialization.
